If you’re using a Full Site Editing (FSE) theme or the block editor, you can add the WPML language switcher using a shortcode within the Navigation block. WPML provides a shortcode for the language switcher, which you can embed directly into the block using the “Shortcode” block. This way, you can display the switcher in the navigation.
WPML can add the language switcher directly to the navigation menu for classic themes via the “Menu” options in the WP Admin under Appearance > Menus. Hopefully, this helps!
Let me know if you need more specific instructions based on your theme setup.
